.eppiication riled January 27, 1914.

To all 10. mm it may concern.

Be it known that 1, CHARLES A. TILLY, a citizen of the United States,and e. resident of New York, borough of Brooklyn, county of Kings, andState of New York, have invented n certain new and useful Improvement inCouplings, of which the following is a full, clear, and exactspecification.

This invention relates to a class oi devices adapted to be used inconjunction with pipes.

My invention has for its object primarily to provide a device, orcoupling designed to be employed especially for connecting the feed pipeend the delivery pipe to meters used for registering the consumption ofwater, gas, and the like in order to prevent one, or both of these pipesbeing disconnected from the meter for the purpose of tampering With theapparatus, or for epplying other devices thereto. This is accom plishedmainly by providing 21 tubular member or pipe adapted to be connected tothe meter through the medium of e locking member, or nut, and providingboth of the members with co-ooting means whereby a.

' sealing device may be employed for sealing breaking theseulin'gelement.

these parts together so as to be prevented from being separately rotatedwithout A further object of the invention is to provide a form ofcoupling combining simlicity end eiiiciency, and which is susceptile 01?being size.

A practical embodiment of the invention is re resented in theaccompanying drawing owning a pert of this specification in whichsimilar characters of reference inclients corresponding parts in ull-theviews, the said invention being more fully described hereinafter, andthen pointed out in the claim at the end of the description.

In the drawing, Figure l is an elevation of one form of meter withoneform' of coupling embodying my invention applied thereto. Fig. 2 isan enlarged fragmentary view, portly broken away, showing the-menner otconnecting the; coupling to the nippleof a meter, and Fig. is on endview of the coupling shown in Fig. 2. p

The device, or coupling has n. tuhulur member, or pipe 10, and e lockingmember, serving to connect the pipe to the nipple 12 of a meter, us 13,which may be Specification ofI-etters la'tent.

any suitable shape and size to adapt it to the consumption of water,gee,-

be connected to the nipple or the meter, and

this pipe is of a form having on one of its ends an annular flange 14extending from its outer periphery. The locking member, or nut 11 isalso of a type having a passage therethrough, and part of the wallofthis The threaded part of the passage 15 is 01" emeter to readilyaccommodate the annular flange 14: of the pipe when guided through thenut, and on one end of the nut and extending inwardly of its passage isan annuler flange 16 provided with one or more slots 17. The opening ofthe annular flange 16 of the nut is slightly larger than the diameter ofthe pipe proper to permit the pipe to be freely movable therethrough,but this flange is of suilicient Width to serve as e'stop for preventingthe flange 14 of the pipe from passing entirely-out of the opening ofthe nut. To connectthe pipe 10 to the nipple of a meter the pipe-jisdirected through the threaded end of the opening of the nut 11 so thatits flanges it will be seated in the nut in a manner to abut against theflange 16. The nut is then screwed by the use of u wrench, or exteriorthreaded end of so that the parts will be tightly fastened together.

. Serving as co-acting means to ermit a.-

sealing device, as 18, to be employe for pre venting the nut and thepipe flOl. being separately rotated when connected to the meter, on theexterior of the pipe 10, and spaced from its flange, is e lug 19 havingan opening 20 therethrough, and in e. suiteble putt of the well of thenut is provided on opening 21. The opening 20 of the pipe and theopening 21. 9f the nut are preferably transversely disposed throughthese parts (it the coupling, and

of the flange of the nut. The sealing device 18 which may be of theusual form having a. Wire, 215-323, is then disposed through both of theopenings 20 and 21, and the free end I when 'ossen'zhling the pipe andthe not together, as above described, the lug i9 is guided through oneof the slots 17' sutlicient di- 1 its or other suitable mate.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination with a meter including a. casinghaving oppositely extending threaded nipples; of a coupling nut on eachof said nipples provided with a transverse aperture at its periphery andhaving a flanged end, a flanged pipe coupled to each of said nipples bysaid nuts thereon and provided with a transversely apertured ear, and alilament passed through the apertures in said coupling nuts andapertures of said ears with the ends thereof joined and sealed, saidfilament passing around the meter.
